3.4 Planning A Skating Party

1. Q. Suppose your class is planning a skating party to celebrate the end of the school year. Your comitte is in charge of finding a place to rent in-line skates for a reasonable price. You get quotes from two companies.
Roll away skates charge $5 per person.
Wheelies skates and stuff charges $100 plus $3 per person.
Which company should you choose if you want to keep the cost to a minimum? Explain how you made your choice.
A. Roll away skates: Y=5x=x=60 Y=5X60 $300
Wheelies skates: Y=3x + 100 x=60
Y= 3 X 60 + 100
Y=180=100
Y= 280 $280

Wheelies skate because it’s the price times the students. For wheelies it was 280 and was 20 dollars cheaper then Roll Away.

1.A What you do for roll away is 5x60 because it’s the cost times the amount of people.For wheelies what you do is 3x60 which is the cost times the amount of people.
C. 1-80,1-40 I choose these because the y axis is 1-4 and the x axis is 1-80.

4. 5
5. Roll away because its cheaper whith more people because its and extra 3$ per person so you already have 300$ plus an entrie fee of 100$ so in all together its more the rollaway.
